Find the cost of fencing around a circular field of diameter 28 m at the rate of Rs.1.50 a meter?

One Answer on this Question

1. In the example first we have to find the area of the field

   we have given the following values ,

   cost of fencing per meter = Rs 1.50

   Diameter of circular field = 28

   We have to find the area , a = ?

   We know that,

   Area = 2 π r

   = 2 x 22/7 x 14

   = 2 x 22 x 2

   = 44 x 2

   = 88 sq. m

   So, area of circle is 88 sq.m

   Now just multiply it with 1.50

   cost of fencing = 88 x 1.50

   = Rs. 132

   So, the cost of fencing the circular field is Rs. 132
